Container security incidents are becoming more common, with nearly one in four respondents to a new survey from BellSoft saying they have experienced a security incident. The survey concluded that questions about security practices remain unresolved. According to the survey by OpenJDK provider BellSoft, 62% of participating developers reported that human errors were the biggest contributors to container security mistakes. Among the key findings in the report, BellSoft wrote, are: Developers ranked shells (54%) and package managers (39%) as the most essential tools inside the base container. Package managers present a particularly critical security concern, as they expand the attack surface both directly and by enabling runtime installation of additional unnecessary components. Combined with other non-essential tools, this creates substantial vulnerability exposure in production environments. A more practical approach is using hardened minimal runtime images, paired with fulle...
